Abstract

This research investigated the effect of light intensity and biofertilizer on the yield, which includes the production of indigo compounds and plant nutrient uptake. The study used a randomized complete block design with a split plot design with 4 levels of light intensity as the main plots and 4 levels of biofertilizer as a sub plots with 3 replications. The combination of light intensity and biofertilizer affects fresh weight, biomass and tissue nitrogen. The highest fresh weight and biomass was found at 100% light intensity with double inoculation of mycorrhizae and rhizobium. Whereas the highest tissue nitrogen was at 10% light intensity with double inoculation of mycorrhizae and rhizobium. The production of indigo affected by light intensity, ie at 10% light intensity indicates the highest indigo. Mycorrhizae and rhizobium have a synergistic relationship as biofertilizer in increasing plant yields and nutrient uptakes in 100% light intensity.
